Low Pass Filter Subwoofer

Low pass filter subwoofer circuit serves to filter out low-frequency tone to the audio system needs super bass tones or more with the name of the subwoofer. Low pass active filter circuit is also referred to as an active subwoofer crossover. Active subwoofer crossover circuit function is to filter the super bass tones to be strengthened in the power amplifier subwoofer. Basically the working principle of the active filter circuit is skipped subwoofer audio signals with low frequencies and attenuate the audio signal above the cut-off point of the low-frequency bass tones. Subwoofer active filter circuit is made using an operational amplifier (Op-Amp) IC TL062 types arranged in a two-level voltage amplifier and active filter configuration. The active filter circuit has a working frequency of 20-100 Hz with the strengthening of up to 80 dB. To make this subwoofer active filter circuit can be seen in a circuit of pictures and a list of components that are used as follows.
